Rendon Holloway recommends James W. Argo

Many thanks to Jim and his team for getting us our home mortgage. In spite of some challenging aspects, it all happened very quickly, and the result was more than satisfactory in terms of both the amount obtained, and the interest rate. Moreover, Jim was very proactive about explaining each step along the way, and was always available to answer questions, both of which made our part of the process easy to complete. Last but not least, Jim is a very friendly person and a pleasure to interact with. In short, highly recommended!

Bridget M. recommends Sean Maley

I cannot say enough wonderful things about Sean and his team. As first time home buyers, my husband and I had many questions and needed lots of hand holding throughout the loan approval and escrow process. Sean was always available, patient, and enthusiastic about taking our phone calls and emails. He made us feel comfortable and well taken care of during a very daunting time in our lives as first time buyers. It was an absolute pleasure working with Sean and I'm so glad we were introduced to him.

Brian T. recommends James W. Argo

Jim was amazing. It was a bit more work upfront for us, but the actual mortgage closing process was exceptionally smooth. Jim was on top of issues as they arose, and often resolved them before we were even aware. Thank you Jim; we’re thrilled to have funded our first house, and give credit here to your efforts!

Noah R recommends Aisling Ferguson

Aisling is amazing to work with - she helped us get our primary home 12 years ago and has been a key partner ever since. She just helped us find our dream home in a very competitive market and I don’t think our offer would’ve been accepted without her. Her ability to get results is unmatched. Couldn’t recommend more.
